Going to buy some lasers… ebay
I emailed the seller about the angle. his response was
For calculations, at 3ft distance from the surface the line length is
between 3.5ft to 4 ft.
So if remember my trig, the calculaton would be arctan X = 1.75/2 =30.25 degrees*2 = 60.5 degrees (at 3.5ft)
Is this correct?
Do you think that this will provide ample coverage with two lasers in opposite corners, or should i shell out the extra 8 bucks and order the 89 degrees from AIXIZ
Thanks
